ClusterTemplate: An object stores template information about the cluster
which is used to create new clusters consistently

Two binaries work together to compose the magnum system. The first binary
(accessed by the python-magnumclient code) is the magnum-api REST server. The
REST server may run as one process or multiple processes. When a REST request
is sent to the client API, the request is sent via AMQP to the
magnum-conductor process. The REST server is horizontally scalable. At this
time, the conductor is limited to one process, but we intend to add horizontal
scalability to the conductor as well.
